IMPROVEMENT IN LAND-ROLLERS.

To all whom it may concern:

Be it known that I, JOHN COLE, of Fredericksburg, in the county ofChickasaw and in the State of Iowa, have invented certain new and usefulImprovements in Land-Roller; and do hereby declare that the following isa full, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereonmaking a part of this specification.

The nature of my invention consists in the construction and arrangementof a land-roller, as

will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itscon-- struction and operation, referring to the annexed drawing, inwhich Figure l is a side view, and Fig. 2 is a plan view of my machine.

A and B B represent three rectangular frames, in which the rollers O andD D, respectively, are placed. These frames with their rollers are arranged in the manner shown in Fig. 2that is, the frame A with its roller0 in front, and the frames B B with their rollers D D on each side andin rear of the frame A. From the front side of each frame B, nearer theinner end, extends a bar, E. This bar E does not extend at right angleswith the frame, but is slightly inclined toward the inner end of thesame. A rod, Gr, passes from near the outer end of the frame B throughthe front end of the bar E, and immediate] y on the other side of saidbar the rod is attached to the projecting end of the front bar of thefront frame A. Another rod, H, connects each frame B with the rear barof the frame A.

It will be noticed that, by the connections of the frames A and B B asthus arranged, the rear rollers D D do not run parallel with the frontrollers (l, but they are slightly turned inward, which reduces thedraft. On the frame A, above the roller 0, is arranged the drivers seatI, and on the hind frames B B, above the rollers D D, are arranged boxesJ J to contain dirt or other material to equalize the weight of thedriver. Thetongue K is attached and braced, in any suitable manner, tothe front of the frame A.

The rollers being set in separate frames attached by theconnecting-bars, each roller works independently of the others. Theywill. work on rough oruneven ground equally as well as on smooth ground,and, when meeting any obstruc tion, the side rollers can be raised so asto pass over the same without going around them.

The operator can roll heavily or lightly by carrying weights in theboxes or running empty to suit the ground.

The rollers can readily be taken apart by unscrewing a few burrs, andthe center roller is then ready to roll walks or narrow places.

Having thus fully described m y invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the frames A and B B, bars E E, and rods G G and H H,and the rollers OD D, constructed and arranged as described, and for thepurposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of September, 1871.

JOHN COLE.
